A lot. As in they've been targeting Boeing, Airbus, etc for a long time now. It's still a lot of work though, even after you've stolen the information. The ability to create modern manufacturing capabilities is a lot harder to steal. British did it to the Chinese many decades earlier of course. Darjeeling tea was mostly developed by stealing the highly coveted tea secrets from China.

Also goes into Chinese telecom hardware that was completely stolen from Cisco, bugs and all. https://www.amazon.com/Cyberspies-History-Surveillance-Hacking-Espionage/dp/1681771543 https://www.amazon.com/Cyberspies-History-Surveillance-Hacki...
